Japanese whisky
Under the JSLMA labelling standards: whisky whose raw materials are limited to malted grains, other cereals and water extracted in Japan, saccharified, fermented and distilled at a distillery in Japan below 95% ABV, matured in Japan at least three years in wooden casks of no more than 700 litres, and bottled in Japan at 40% ABV or more.
Where it is defined
NOT law. JSLMA 'Standards for Labeling Japanese Whisky', Art. 5, effective 1 April 2021, transition ended 31 March 2024. The statutory definition is Liquor Tax Act (Act No. 6 of 1953), Art. 3(15).
Often confused with the Scotch legal definition
The Scotch rules are a statutory instrument enforced with criminal penalties. The Japanese rules are voluntary self-regulation administered by a trade association and bind only its members — a non-member can label imported bulk spirit 'Japanese whisky' without breaching any law.
Worth knowing
Japan's actual statute is far looser: Art. 3(15)(ハ) lets 'whisky' include malt distillate with added alcohol, spirits, flavourings, colourings or water provided the malt distillate contributes at least 10% of total alcohol — and imposes no maturation requirement whatsoever.
